1.1 Moves the location of all of the classes and renames NSFetchRequest+DCTInitMethods.h/m to NSFetchRequest+DCTExtras.h/m so you may need to jiggle things about when updating.

Features

Convenience methods for fetching from the managed object context

Automated creation of managed objects from an NSDictionary representation

A category to handle the ordering of related objects

Asynchronous tasks and fetching with blocks

Convenience methods for asynchronously fetching from the managed object context

NSManagedObjectContext (DCTDataFetching)

Fetching from the context the way it always should have been! Lots of methods to ease the pain of fetching objects from a managed object context.

Also includes an easy way to insert a new object. This will likely be moved to a separate category in the future.

NSManagedObject (DCTAutomatedSetup)

Category to enable a subclass of NSManagedObject to conform to the DCTManagedObjectAutomatedSetup protocol and take a dictionary to generate its values.

There are a number of methods subclasses can implement that will aid the setup process, I talk about these on my blog post.

NSManagedObjectContext (DCTAsynchronousTasks)

Adds methods to perform tasks off the main thread using GCD queues.

The first set allow you to pass a block, in which you can access the threaded managed object context, to perform the task in another queue.

The second set allow you to execute a fetch request on another GCD queue, which will call the given block when done with any objects fetched and an error if there is one. This method returns objects managed in the managed object context called on.

NSManagedObjectContext (DCTAsynchronousDataFetching)

Similar to the DCTDataFetching category on NSManagedObjectContext, but performed using the asynchronous fetch from the DCTAsynchronousTasks category.

Branch Structure

There is a new branch structure for DCTCoreData 2.0, master and demo. Unlike previous versions, master is now the branch to use as a submodule.

master

The master branch contains the code and should be used if you want to add these extensions as a git submodule in other projects. It will only contain the class files themselves without the Xcode project or example classes. This is preferable as it will keep your directories clean of any code which is unnecessary to your working project.

To add this project as a submodule you should run the following from inside your project’s git repository:

git submodule add git://github.com/danielctull/DCTCoreData.git

To keep up to date with the latest changes `cd` into the directory that contains this submodule and pull the newest changes as usual:

git pull origin

demo

This contains an Xcode project that demonstrates the code and is the branch to use to see how to use the code. The demo branch contains a submodule reference to the master branch to bring in the library classes.

To clone the demo branch, while also pulling in any necessary submodules run the following command:
